DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates to civil engineering or construction work.
Site, etc., attached to the work site top, the field to protect the rain, wind, from snow, according to the assembly method of the temporary set roof and temporary roof used to measure the facilitation of work.

[0002]

2. Description of the Related Art Civil engineering and construction work are mostly performed outdoors, and are affected by natural conditions such as rain, wind, and snow. This causes factors such as an increase in construction costs due to a delay in the process or a decrease in the operation rate. In addition, outdoor work during rainfall or in winter not only impairs the health of workers, but also causes unforeseen accidents such as slipping and falling due to deterioration of the working environment.

[0003] In recent years, a scaffold has been assembled so as to surround the entire structure or a part of the site, and a temporary roof is placed thereon.
To form a multiply sheet, or which prevent rain snow to place temporary roof air inflated type on the scaffold have been proposed.

[0004]

However, the conventional temporary roof has the following problems and has been desired to be improved. That is, since the building site or the housing construction site in an urban area has a narrow site site and is surrounded by adjacent structures , a scaffold is assembled around the site, and a temporary roof is placed thereon. It is extremely difficult to install. Also, the construction site as described above has a narrow material loading road, and even if a scaffold is assembled, heavy equipment such as a large crane that transports the roofing material onto the scaffolding cannot enter, and the roofing material must be divided. Transport on the scaffold, assemble the roof on the scaffold, and perform dangerous altitude work. Although the air-expanded roof is lightweight, the fixing method is not only complicated, but also it is necessary to install air pipes for maintaining the inflation.

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned drawbacks of the related art. It is an object of the present invention to provide a lightweight and strong temporary roof, and to provide a work space which requires the temporary roof. It is to provide an assembly Ru method easily to the top.

[0006]

In order to achieve the above object, a temporary roof according to the present invention is provided with a work space required at the time of construction.
A temporary roof erected on the top, wherein the temporary roof is
A predetermined number of mountain-shaped roofing materials (3
a) and a column (3b) integrally joined to the roof material;

Guide the frame that has been free standing on the rail
After moving a predetermined distance,
The space between the frames is connected by an intermediate material such as a purlin girder and breath, and
It is possible to construct a temporary roof by extending roof sheets between frames.
And features .

In the temporary roof according to the present invention, since the main frame, which is a main member, is formed of a hollow long aluminum material, the roof itself can be reduced in weight. The method of the present invention, Guy arranged in parallel wife type frame assembled in advance ground
Drains are placed sequentially from one end of the
The frame was allowed to guide the rail by a predetermined distance moved <br/> movement, the inter-frame after destination of adjacent thereafter and fixedly connected to the same span between material in such purlins and breath
In addition, since the sheet is spread between the adjacent wife-shaped frames , it is easy to install the temporary roof in a narrow place.

Hook 32 and fix it. In addition, roof breath 29
Erod 30 is a block fixed to roof material 3a of the wife-shaped frame.
Tighten to racket 33 using turnbuckle 34
(See FIGS. 2 and 5).

As described above, the frame structure of the temporary roof (small
Is completed for one unit. Next, wife type frame 3
A roof sheet 4 is stretched between A and 3B. Roof sheet 4
As an example, the surface of a polyester blended canvas is
Coated with vinyl chloride, waterproofed and covered
With a thickness of about 0.5mm to 0.7mm
You. As shown in FIG. 12, the roof sheet 4
Slightly wider than the distance between the mold frames 3A and 3B,
On both sides in the longitudinal direction of the
It is inserted through a guide groove 7 formed on the longitudinal side surface of the mold member 6.
Retaining member 35 is attached. This stop
The members 35, 35 into the guide grooves 7, 7
With this, the sheet is spread between the wife-shaped frames 3A and 3B in a planar shape.
It is configured to be stretched and held . Roof sheet 4
When the expansion of the frame is completed, the frames 3A and 3B are
Along the traveling member to the end of the site
At the specified installation position, as shown in FIGS.
It is fixed with the hopper 26a.

If the frames 3A and 3B are fixed
If you repeat the same work as above,
Wife-shaped frames 3B and 3C, 3C and 3D,
3D and 3E, and between 3E and 3F, respectively
Attach purlin 27, purlin girder 27a and eave girder 28
After reinforcing with fubreth 29 and tie rod 30
The entire assembly is completed by expanding the
The temporary roof 1 is constructed on the upper surface of the site. Where the roof sheet
FIG. 12 shows a method for extending the frame between the frames 3A and 3B.
To be more specific, the sheet 4 is fixed to the end in the longitudinal direction.
Attach each of the ropes 36 to the ring 36a
This rope 36 is hand-wound from the opposite eaves side.
When the sheet is wound using a punch (not shown), the sheet 5 is removed.
Clamping members 35, 35 move inside grooves 7 of frames 3A, 3B.
The sheet 4 slides while being pulled by the rope 36, and the sheet 4 is flexed.
It is extended between the arms 3A and 3B (see FIG. 13). Another
If necessary, the side sheet 37 and the gable sheet 3 are provided on the side wall.
8 can also be installed (see FIG. 2). in this case
Also, the side surfaces of the profile members constituting the roof member 3a and the support 3b
The guide groove 7 is used. Prevents loosening of sheet 4
The lower part of the seat located on the eaves has a double structure to
A cuff made of steel pipe or the like is attached to the end of the outer sheet 4a.
Attach the weight bar 39 or use the ratchet mechanism
With the tightened jig 40 (see FIG. 13).
See ).

In the above-described embodiment, an example is shown in which the temporary roof of the present invention is used in a construction site of an underground structure.
It is not limited to this. Houses, it is also possible to assemble using the building construction site, temporary roof 51 in assembled scaffold 50 was laid on site as shown in FIG. 14 in this case
Can be supported. In addition, the temporary roof 60 according to the present invention.
As shown in FIG. 15, by lengthening (tall) the column 61 attached to the eaves side, it is possible to secure a work space not only for curing the construction site but also as an indoor sports ground and an event hall.

[0019]

As described above, the present invention has the following advantages. Wife-shaped frame, the main member, is made of hollow aluminum alloy
Since the temporary roof is made of lightweight,
High corrosion resistance and high strength against wind pressure. That
Provided on both ears of the roof sheet in the guide groove of the roof material
